i bought mine from machv.com...they were $80 shipped, mine were the red stuff ones though. I liked em alot, but i went with Axxis Metal Masters when i upgraded to x-drilled and slotted rotors and stainless lines. I love them too...both didn't have much break dust, as far as i can tell. The Red Stuff pads i wasn't too impressed with as far as dust, there was still quite a bit coming off of them. I realize you will always have some, but they weren't much different then regular pads in taht department.
i have stainless lines with xdrilled and slotted rotors with the metal masters...all i had was regular rotors with my ebc's...so i couldn't give a fair comparison...but i have absolutely no complaints on my metal masters...they definately rock. I hear ceramic pads are pretty good with slotted rotors...don't quote me on that though.
